1) write a gui-based program that allows the user to convert temperature values between degrees fahrenheit and degrees celsius. the interface should have labeled entry fields for these two values. these components should be arranged in a grid where the labels occupy the first row and the correspon- ding fields occupy the second row. at start-up, the fahrenheit field should contain 32.0, and the celsius field should contain 0.0. the third row in the window contains two command buttons, labeled > > > > and < < < < . whenthe user presses the first button, the program should use the data in the fahrenheit field to compute the celsius value, which should then be output to the celsius field. the second button should perform the inverse function.

Suppose there is a relation r(a, b, c) with a b+-tree index with search keys (a, b).1. what is the worst-case cost of finding records satisfying 10 < a < 50 using this index, in terms of the number of records n1, retrieved and the height h of the tree? 2. what is the worst-case cost of finding records satisfying 10 < a < 50 and 5 < b < 10 using this index, in terms of the number of records n2 that satisfy this selection, as well as n1 and h defined above? 3. under what conditions on n1 and n2, would the index be an efficient way of finding records satisfying the condition from part (2)?
